Technical Field

[0001] The utility model relates to the field of gear hobbing machines, in particular to a synchronous double-drive workpiece rotating gear hobbing machine. Background Art

[0002] The synchronous dual-drive workpiece rotation gear hobbing machine is a high-precision processing equipment that uses a dual-drive system to achieve synchronous rotation of the workpiece to ensure extremely high accuracy and stability during the gear hobbing process.

[0003] During the machining process, the workpiece is mounted on two synchronized drive systems, which are controlled by independent drivers to ensure that the workpiece rotates at a predetermined speed and direction. At the same time, the tool holder of the gear hobbing machine moves over the workpiece, and the cutting tool contacts the workpiece surface to perform high-precision gear hobbing. When the workpiece rotates synchronously relative to the controller, most of the joints are not equipped with a positioning structure. Therefore, in order to further ensure the stability of the workpiece during rotation, a synchronized dual-drive workpiece rotation gear hobbing machine is proposed. Utility Model Content

[0011] Preferably, the first chuck cooperates with the first connecting rod to compress the first built-in oil cylinder spring, and the second chuck cooperates with the second connecting rod to compress the second built-in oil cylinder spring to loosen the workpiece.

[0012] Preferably, the first bracket controls the first built-in oil cylinder and the first connecting rod on the first driving mechanism, and the second bracket controls the second built-in oil cylinder and the second connecting rod on the second driving mechanism to move independently.

[0013] Preferably, the first driving mechanism is driven synchronously with the first built-in oil cylinder to rotate the workpiece.

[0014] Preferably, a material guiding channel with a built-in pad and an extended material channel is provided on the first bracket and the second bracket, and the material guiding channel is located directly below the connection between the first clamp and the second clamp.
